Abstract

Se proporciona una tela no tejida que contiene al menos una primera capa homogénea que consiste en una mezcla de al menos una de fibras vegetales naturales desfibradas, fibras vegetales naturales individualizadas y fibras cortadas. La tela no tejida no contiene fibras aglutinantes, adhesivas o de unión térmica, y un peso base de la al menos una capa homogénea es de 20 g/m2 a 100 g/m2 . Cuando la longitud promedio ponderada de la fibra de la al menos una de las fibras vegetales naturales desfibradas, las fibras vegetales naturales individualizadas y las fibras cortadas es mayor de alrededor de 4,0 mm, la tela no tejida es un producto no dispersable que no cumple el requisito de dispersabilidad de acuerdo con INDA/EDANA GD4, y cuando la longitud promedio ponderada de la fibra de la al menos una de las fibras vegetales naturales desfibradas, las fibras vegetales naturales individualizadas y las fibras cortadas es menor de alrededor de 4,0 mm, la tela no tejida es un producto dispersable como se define de acuerdo con INDA/EDANA GD4. Se proporcionan métodos para preparar la tela no tejida.A nonwoven fabric is provided that contains at least a first homogeneous layer consisting of a blend of at least one of defibrated natural plant fibers, individualized natural plant fibers, and staple fibers. The nonwoven fabric does not contain binder, adhesive or thermal bonding fibers, and a basis weight of the at least one homogeneous layer is from 20 g/m2 to 100 g/m2. When the weighted average fiber length of the at least one of the defibrated natural plant fibers, the individualized natural plant fibers and the staple fibers is greater than about 4.0 mm, the nonwoven fabric is a non-dispersible product that does not meets the dispersibility requirement according to INDA/EDANA GD4, and when the weighted average fiber length of the at least one of the defibrated natural vegetable fibers, the individualized natural vegetable fibers and the staple fibers is less than about 4, 0 mm, the nonwoven fabric is a dispersible product as defined in accordance with INDA/EDANA GD4. Methods for preparing the nonwoven fabric are provided.
